IHRA Classification guide
 

Anybody know how to find the IHRA stock and superstock classification guide?

Pretty sure you can basically use the NHRA guide, which is based on the factory HP. You may have to contact an IHRA tech for the factored HP. If you can get to an IHRA ProAM, they have the books in the tech trailer - at least in Division 9. I have never found the IHRA classification guide online.

Here's a link to the horsepower adjustments listed on the IHRA website. You'll need to use the "find" command ( Ctrl+F) with your browser to locate what you're looking for, as all the listings, plus OR minus, are chronological -

Bob,

I had a IHRA HP question and Danny Waters helped me. The HP isn't posted anywhere on line, so far as I know. I have heard that IHRA classification guide has no Caddies list. LOL

Marty,
That's OK. I don't have a Caddy anymore.

FWIW, during the Rocky Mountain Nationals in Edmonton, Tech was using the NHRA guide. if you asked a question regarding a combination HP factor, those sheets came up, with no reference to NHRA. This, even though certain combinations can be found on the IHRA web site with lower HP factors than NHRA. IE 94-97 LT1, 74-76 Chev 400, and the 1965 327-250. Not sure if it was for this race only . or if they are standardizing between the 2 HRA's
